| Abstract: | Constraint function of lateral deformation, insulation, load lowering, stress diffusion of geosynthetics reinforcement cushion are introduced. According to its reinforcement mechanism and soft ground character,Terzaghi bearing capacity formula is improved. Corrected formula of bearing capacity of reinforcement cushion is obtained. Corrected formula is proved to be effective via analyzing and contrasting project example. The above is valuable to study of reinforcement mechanism and designing calculation of reinforcement cushion. |
